Reduce maintenance downtime in your industrial equipment by protecting it with this safety relay from Phoenix Contact. It uses force-guided contact to monitor circuits, cutting off power if it detects a malfunction. A green LED signal lets you easily check its status and operating voltage.
This device has a broad switching voltage range between 15 and 250V AC/DC, which makes it suitable for both low-voltage and high-voltage applications. Its silver-tin-oxide contacts are highly conductive and deliver reliable switching.
As the relay is compatible with both single-channel and two-channel devices, it's a versatile option. A quick one-second recovery time means you can depend on it for rapid use in demanding applications. For added durability, it's housed in polyamide, which is corrosion-resistant and safe to use in damp environments. Choose this relay to regulate emergency stops and doors.

• Wide operating temperature range between -20°C and +55°C for use in harsh environments
• Mechanical durability of 10,000,000 cycles for long-term use
• IP20 (ingress protection) rating means it's touch-proof
• Shock and vibration resistant for use with heavy-duty equipment
